History
Obtaining a careful history is very helpful in the localization of lesions causing Horner syndrome.
- First-order neuron lesions may be associated with signs and symptoms such as hemisensory loss, dysarthria, dysphagia, ataxia, vertigo, and nystagmus.
- Second-order neuron lesions may be preceded by trauma and may be accompanied by facial, neck, axillary, shoulder or arm pain, cough, hemoptysis, history of thoracic or neck surgery, history of chest tube or central venous catheter placement, or neck swelling.
- Symptoms associated with third-order neuron lesions include diplopia from sixth nerve palsy, numbness in the distribution of the first or second division of the trigeminal nerve, and pain.
- The presence, absence, and/or location of anhydrosis is an important localizing sign that may be elicited from the history.
- Although Horner syndrome is commonly an incidental finding related to a benign cause, it occasionally may be a manifestation of a serious and life-threatening disorder. Careful direction of the history to rule out such life-threatening disorders is of the utmost importance (see Causes).
Physical
- Important aspects of the physical examination include the following:
- Measurement of pupillary diameter in dim and bright light and their reactivity to light and accommodation
- Examination of the upper lids for ptosis
- Examination of the lower lids for upside-down ptosis (eg, position of the lower lid with respect to the inferior limbus)
- Extraocular movements
- Biomicroscopic examination of the pupillary margin and iris structure and color
- Confrontational visual field testing and testing of facial sensation
- Observation for the presence of nystagmus, facial swelling, lymphadenopathy, or vesicular eruptions
Causes
- First-order neuron lesions
- Arnold-Chiari malformation
- Basal meningitis (eg, syphilis)
- Basal skull tumors
- Cerebral vascular accident (CVA)/Wallenberg syndrome (lateral medullary syndrome)
- Demyelinating disease (eg, multiple sclerosis)
- Intrapontine hemorrhage
- Neck trauma (eg, traumatic dislocation of cervical vertebrae, traumatic dissection of the vertebral artery)
- Pituitary tumor
- Syringomyelia
- Second-order neuron lesions
- Pancoast tumor (tumor in the apex of the lung - most commonly squamous cell carcinoma)
- Birth trauma with injury to lower brachial plexus
- Cervical rib
- Aneurysm/dissection of aorta
- Subclavian or common carotid artery
- Central venous catheterization
- Trauma/surgical injury (eg, radical neck dissection, thyroidectomy, carotid angiography, coronary artery bypass graft)
- Chest tubes
- Lymphadenopathy (eg, Hodgkin disease, leukemia, tuberculosis, mediastinal tumors)
- Mandibular tooth abscess
- Lesions of the middle ear (eg, acute otitis media)
- Neuroblastoma[2]
- Third-order neuron lesions
- Internal carotid artery dissection (associated with sudden ipsilateral face and/or neck pain)[3]
- Raeder syndrome (paratrigeminal syndrome) - Oculosympathetic paresis and ipsilateral facial pain with variable involvement of the trigeminal and oculomotor nerves
- Carotid cavernous fistula
- Cluster/migraine headaches
- Herpes zoster
